Given how much everything else with a Gibson logo has risen in price, the 1.500 bucks are an ok offer, especially as condition looks very good. That doesn't change the fact of course that those Melody Makers do have a cheesy feel to them, both my earlier sixties EBs and my later slotheads feel more like real, lovingly produced instruments in comparison. (Same goes for the seventies maple necks.)
The Melody Maker is not too far removed from a Kalamazoo or Danelectro feel, I find even the various SBs more substantial and valuable in feel.
But if you are really set on having one of those here, I guess you could do a lot worse.
